Filamentous abrasive crevice cleaner

ABSTRACT

Apparatus and associated methods relate to a fibrillous abrasive crevice cleaner (FACC). In an illustrative example, a fibrillous abrasive tip may be made of a continuous combination of steel wool and wire. For example, the FACC may include a twisted multistrand handle extending from a distal end to a proximal end along a longitudinal axis. The FACC may include a continuous fibrillous mass fixedly coupled about the distal end of the twisted multistrand handle, such that the fibrillous mass forms a knot distal to the proximal end of the twisted multistrand handle. For example, the FACC may include a proximal end of the fibrillous mass captured between the twisted multistrand handle. The formed knot around the distal end of the twisted multistranded handle and the fibrillous mass being entwined into the handle may, for example, advantageously resist decoupling of the fibrillous mass from the twisted multistrand handle.

TECHNICAL FIELD

Various embodiments generally relate to cleaning objects.

BACKGROUND

Cleaning removes unwanted substances from an object or environment, such as dirt, infectious agents, and other impurities. Swabs are handheld items that consist of one or two wads of material wrapped around one or both ends of a short rod made of wood, rolled paper, or plastic. Cotton swabs may be used as a cleaning tool for household purposes. Steel wool may be useful in cleaning and polishing metal for functional or ornamental purposes. Often polishing and buffing with an abrasive are the finishing processes for smoothing a workpiece's surface. Polishing may remove oxidation to create a reflective surface or prevent corrosion on metal surfaces. Polished metal surfaces may be coated with wax, oil, and/or lacquer to avoid unwanted oxidation of the metal.

SUMMARY

The FACC may include a continuous fibrillous mass fixedly coupled about the distal end of the twisted multistrand handle, such that the fibrillous mass forms a knot distal to the proximal end of the twisted multistrand handle. For example, the FACC may include a proximal end of the fibrillous mass captured between the twisted multistrand handle.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

To aid understanding, this document is organized as follows. First, to help introduce a discussion of various embodiments, a cleaning system using an exemplary fibrillous abrasive crevice cleaner (FACC) is presented in FIG. 1A-B. Second, regarding FIG. 2A-5B, this document describes exemplary apparatus and methods useful for making a FACC. Third, that introduction leads into a description regarding FIGS. 6-7B of some exemplary embodiments of an exemplary FACC. Finally, relating to FIGS. 8-12 , the discussion turns to exemplary embodiments that illustrate various implementations of an exemplary FACC.

FIG. 1A depicts an exemplary FACC 100 employed in an illustrative use-case scenario. In this illustrative scenario, the FACC 100 removes deposits within a cavity 105 of an object 110 by entering a narrow crevice 115 of the object 110. For example, the object 110 may be a carburetor tube having a narrow crevice (e.g., a ledge with an inner corner). The object may, for example, come from a motor vehicle 120. The motor vehicle may, for example, be a boat, a bus, a car, a lawnmower, or a plane. In some examples, the deposit may be hardened fuel sediments deposited on an inner surface of the carburetor tube.

As shown in FIG. 1A, the FACC 100 includes a fibrillous abrasive tip 125 and a multistrand handle 130. In some implementations, other fibrillous abrasive materials strong enough to remove deposits from the cavity 105 may be used. For example, the fibrillous abrasive tip 125 may be steel wool. For example, a brass wool swab may be used for the abrasive tip.

An exploded quarter-sectional close-up view 135 of the interlocking of the abrasive tip 125 and the multistrand handle 130. A fibrillous mass 140 is coupled continuously along the multistrand handle 130. The fibrillous mass 140 forms a knot 145 along the bending tip of the multistrand handle 130.

FIG. 1B depicts a close-up sectional view of an exemplary FACC employed in an illustrative scenario 150. In illustrative scenario 150, the FACC 100 may be applied. The FACC 100 may be pressed upon with a force F on the object 110. The FACC 100 includes the fibrillous abrasive tip 125. The abrasive tip 125 may include the twisted multistrand handle 130. The fibrillous abrasive tip 125 may include the fibrillous mass 140. The fibrillous mass 140 may form a knot 145 around the twisted multistrand handle 135.

As the force F is applied to the FACC, the fibrillous mass prevents the twisted multistrand hand from contacting the object. The fibrillous mass may prevent unintended scarping of the twisted multistrand handle against an object. The twisted multistrand handle 130 and the object 110 are set apart at a distance d. The distance d shows a buffering zone between the object 110 and the multistrand handle 135. The buffering zone may be created by including the fibrillous mass separating the multistrand handle.

In various embodiments, the fibrillous abrasive materials may be conformable to narrow crevices 115. For example, different abrasive filaments may be suitable for cleaning reactive chemicals.

Some implementations may attach abrasive grit materials to the fibrillous abrasive tip 125. For example, the fibrillous abrasive tip may include a non-abrasive polymeric filament and abrasive grits attached to and/or embedded in the polymeric filament. For example, the abrasive grits may facilitate deposit removal in the cavity 105.

In some examples, the abrasive grit may include garnet, diamond, silicon carbide, aluminum oxide, and/or other abrasive grit materials. Various abrasive grits may be suitable for cleaning different surfaces and/or deposits in multiple implementations.

In this example, the fibrillous abrasive tip 125 has a teardrop shape. In some implementations, the teardrop-shaped fibrillous abrasive tip 125 may provide a substantial surface area for removing deposits in the cavity 105. In some examples, the teardrop-shaped fibrillous abrasive tip 125 may provide a buffer between the handle 130 and the surface of the fibrillous abrasive tip 125. For example, the buffer may prevent the handle 130 from displacing through the fibrillous abrasive tip 125.

In various embodiments, the handle 130 may be malleable to reach within cavities and through crevices of multiple shapes. The handle 130 may, for example, be a wire handle. The handle 130 may, for example, be a bendable brass wire handle. For example, the brass wire handle may be scrape resistant to the cavity 105. For example, the cavity 105 may remain unscratched when the wire handle 130 is scraped against the surface of the cavity 105.

Accordingly, the FACC 100 may, for example, be used to clean fuel sediments within a cavity through a narrow cervix. In some implementations, the FACC 100 may advantageously be strong enough to remove substantially uniformly harder deposits on a surface of the cavity 105 while significantly preventing damage to the cavity surface.

In some embodiments, an opposite end of the FACC from the fibrillous abrasive may, for example, be coated. The coating may be a polymer. For example, the coating may be a (curable) liquid polymer. In some embodiments, the coating may, for example, advantageously prevent injury to a user by sharp and/or exposed ends of a twisted multistrand handle

FIG. 2A is an illustrative method for fixedly coupling a continuous fibrillous mass to a twisted multistrand handle creating a FACC. FIG. 2B depicts a flowchart for an exemplary method for fixedly coupling a continuous fibrillous mass to a twisted multistrand handle, making a FACC.

Both FIG. 2A and FIG. 2B illustrate exemplary method 200 for making a FACC by mechanically combining fibrillous mass and a wire handle. In this example, a wire is prepared in step 205. For example, the wire may be a brass wire. In various implementations, the wire may be a malleable material suitable for bending and twisting. In some embodiments, the wire may, for example, be a steel wire. In some embodiments, the wire may be stainless steel. Such embodiments may, for example, advantageously reduce or eliminate a chemical reaction of the handle with chemicals the FACC is exposed to during cleaning. In some embodiments, the handle may, for example, be a malleable polymer.

Next, in step 210, a fibrillous abrasive material is captured in the wire. In step 215, the fibrillous abrasive material is tightly wrapped around the wire. In some examples, the fibrillous abrasive material may be steel wool.

In step 220, the wire is twisted, and the fibrillous abrasive material's loose ends are twisted along with the wire. In some examples, the loose ends of the fibrillous abrasive material may create a mechanical bind for the twisted wire.

In step 225, the wire is twisted tightly to form a handle for the FACC. For example, the fibrillous abrasive material may form a teardrop shape. Finally, in step 230, both ends of the twisted wire are tied together to provide easy handling and hide the wire's sharp ends. Accordingly, the FACC 100 may be manufactured substantially mechanically. For example, the attachment between the stem and the fibrillous abrasive tip may advantageously be resistant to chemicals and/or solvents.

In various embodiments, the exemplary method 200 may, for example, be performed manually. In some embodiments, the exemplary method 200 may, for example, be at least partially performed automatically. For example, a robotic cell may be configured to cut and/or shape the wire. For example, the fibrillous abrasive material may be blown and/or sprayed on the wire. In some embodiments, an end effector (e.g., a gripping tool or a chuck) may engage the wire (e.g., at the ends) and twist the handle, as shown in steps 220-225. Such embodiments may, for example, advantageously reduce manufacturing costs and/or increase manufacturing speed.

FIG. 2C is an illustrative method depicting the creation of an exemplary knot in a FACC. FIG. 2D is a flowchart depicting an exemplary method used to create an exemplary knot in a FACC. Both FIG. 2C and FIG. 2D illustrates an exemplary method 235 for knotting the fibrillous mass to a twisted multistrand handle. For example, in exemplary step 240, a fibrillous mass 240 a is pulled into the fold ends of a wire 240 b.

Next, in step 245, the fibrillous mass becomes a knotted fibrillous mass 245 a. In step 250, the fibrillous mass is wrapped around itself to form a first loop 250 a. In step 255, the fibrillous mass is wrapped around itself again to form a second loop 255 a.

In step 260, the tag ends 260 of the fibrillous mass are pulled tight to sinch down first loop 250 a and second loop 255 a to form a wrapped fibrillous mass 255 b. In step 265, the tag ends 260 a of the fibrillous mass are wrapped around the fold ends of a wire 240 b.

Next, in step 270, the fold end of the wires 240 b are twisted to form a twisted multistrand handle, with the fold ends of the wire becoming crimped wires 270 a.

In step 275, the fold ends of the wire 240 b and may be wrapped around a twisted handle 275 a. The twisted handle may, for example, be created by twisting the manifolds to any length by twisting the fold ends of the wire. By way of example and not limitation, the length of the twisted wire may be between 3-6 inches.

In step 280, the tag ends 260 a of the fibrillous mass, and any extra fold ends of the wire 240 b are cut completely from the twisted handle 275 a.

In various embodiments, the exemplary method 235 may, for example, be performed manually. In some embodiments, the exemplary method 235 may, for example, be at least partially performed automatically. For example, a robotic cell may be configured to cut and/or shape the wire. For example, the fibrillous abrasive material may be blown and/or sprayed on the wire. In some embodiments, an end effector (e.g., a gripping tool, a chuck) may engage the wire (e.g., at the ends) and twist the handle, as shown in steps 270-275. Such embodiments may, for example, advantageously reduce manufacturing costs and/or increase manufacturing speed.

FIG. 3A is an illustrative method 300 used to create a second abrasive tip with a second fibrous material in a FACC. FIG. 3B a flowchart depicting an exemplary method 300 used to create a second abrasive tip with a second fibrous material in a FACC. In step 305, a twisted wire handle 305 is prepared. This may, for example, include the creation of an abrasive tip by knotting fibrillous mass to a distal end of a twisted multistrand handle, as outlined in FIG. 2A-2D.

In step 310, the proximal end of the twisted is bent. The bending may, for example, allow a second fibrillous abrasive to couple the proximal end of the FACC. In step 315, couple a second fibrillous abrasive to the proximal end of the FACC. Next, in step 320, form a first loop with the tag ends of the fibrillous abrasive around the bent proximal end of the FACC. In step 325, for a second loop with the tag ends of the fibrillous abrasive around the bent end of the FACC. Next, in step 330, form an abrasive tip by continuously twirling the tag ends of the abrasive material 330 a around the proximal end of the twisted multistrand handle. The abrasive tip size and shape may be altered to suit different functionalities. Such functionalities may include polishing jewelry, cleaning a carburetor, or polishing other objects. Next, in step 335, bend the proximal end of the twisted multistrand handle unto itself. Pressure from bending the proximal handle to itself may keep the second abrasive tip from falling apart. In step 340, cut away the excess fibrillous mass.

FIG. 4A is an illustrative method 400 used to create a second abrasive tip in a FACC. FIG. 4B a flowchart depicting an exemplary method 400 used to create a second abrasive tip in a FACC. Exemplary method 400 begins with an embodiment of a FACC, including a twisted multistrand handle 400 a. The proximal end of the twisted multistrand handle includes fold wire ends 400 b. The twisted multistrand handle 400 a may, at its distal end, contain a first abrasive tip 400 d. The twisted multistrand 400 b may contain fibrillous mass tag ends 400 c from forming the first abrasive tip 400 d. The formation of the first abrasive tip 400 d may, for example, be shown in FIGS. 2A-2D.

In step 405, the tag ends 400 c of the fibrillous mass and may first loop around the proximal fold wire ends 400 b. In step 410, a second loop may be formed with the tag ending 400 c of the fibrillous mass. In step 415, a second abrasive tip 415 a may form. After forming the second abrasive tip 415 a, there may be excess tag ends 415 b of fibrillous mass. In step 420, excessive tag ends 415 b of fibrillous mass is removed from the second abrasive tip. In step 425, an adhesive, pressure, or epoxy may be applied to ensure the second abrasive tip does not fall apart. For example, pressure may be applied to the proximal fold wire ends 400 b to bend the ends together, securing the fibrillous mass. An epoxy may coat the second abrasive tip to seal the tip. This may, for example, give a user the ability to use a chemical-resistant FACC with a first abrasive tip based on a mechanical coupling and a second abrasive tip based on a chemically induced coupling. An adhesive may, for example, be used to bind the second abrasive tip together.

FIG. 5A is an illustrative method for attaching a fibrillous mass to create a second abrasive tip in a FACC. FIG. 5B is a flowchart depicting an exemplary method for attaching a fibrillous mass to create a second abrasive tip in a FACC.

Both FIG. 5A and FIG. 5B show an exemplary method 500 for attaching a filamentous material 500 c to a multistrand shaft 500 a. In this example, the filamentous material 500 c is captured in a filament receiving slit 500 b composed of the fold end of the twisted multistrand wire 500 a. The twisted multistrand handle may, for example, from methods 2A-2D, already have a first abrasive tip 500 d.

In step 505, an abrasive material from either the twisted multistrand or a second source is twisted around the fold ends of the twisted multistrand handle with epoxy and/or an adhesive. Next, in step 510, the twisted multistrand handle twirls the abrasive material to form a second abrasive tip. In step 515, epoxy is added to secure the second abrasive tip before the final wrap. In the alternative, in step 515, pressure may be applied to the fold end of the wires to seal the abrasive material. In the alternative, in step 515, the entire second abrasive tip may be sealed with epoxy to secure the abrasive tip. Combinations of pressure, adhesive, knots and epoxy may, for example, be used to seal 515 a the second abrasive tip. In step 520, the base of the tip is secured. In step 520, the second abrasive end is cleaned up, and any excess fibrillous material is removed.

In some embodiments, the twisted multistrand handle may be scrape resistant against cavity surfaces. In some embodiments, the twisted multistrand handle may, for example, be a polymeric shaft. Such embodiments may, for example, advantageously provide decreased cost, increased manufacturability, and/or scratch resistance. In some embodiments, the twisted multistrand handle may be a steel shaft. Such embodiments may, for example, advantageously provide bending resistance after creation.

In some embodiments, the attaching material may be glue. In some examples, the attaching material may be hot plastic. For example, Plasti Dip may be applied to the contact area to hold the filamentous material and the twisted multistrand together for the second tip.

Some embodiments may choose an attaching material according to a target application (e.g., based on solvents and/or other chemicals that the junction is expected to be exposed to). For example, the attaching material may be chosen to be resistant to expected chemicals. In some embodiments, an attaching material may, for example, be epoxy.

In some embodiments, the attaching material may provide a mechanical connection. For example, in some embodiments, a compression fitting may be provided. As an illustrative example, a crimp sleeve/collar may be applied partially around the proximal end of the twisted multistrand handle to mechanically capture the filamentous material to the shaft of the twisted multistrand handle.

In some implementations, the amount of filamentous material may depend on the size requirement of the filamentous abrasive tip.

In some embodiments, the fixation material may be solvent-resistant such that the fixation material may not decompose during use. In some embodiments, a fixation material may include a mechanical connection. In some embodiments, the filamentous abrasive tip may form a teardrop shape.

FIG. 6 shows cross-sectional views of an array 600 of exemplary filament tips of various shapes and sizes. In some implementations, a user may selectively choose a size of the array 600 of filament tips accordingly to the user's need.

For example, some embodiments may be advantageously configured for small applications, such as jewelry cleaning. For example, out of the array 600 an exemplary tip 605 may be used to clean a small piece of jewelry. The abrasive tip 605 is created with a narrow tip because the fold ends of the wires have no spacing.

In some embodiments, out of the array 600 of tips, an exemplary abrasive tip 610 may, for example, be used to clean jewelry. The abrasive tip 610 is conical. For example, the conical shape of the abrasive tip 610 may push out dirt in a piece of jewelry.

In some embodiments, out of the array 600 of tips, an exemplary abrasive tip 615 may, for example, be used to clean a carburetor. The exemplary abrasive tip 615 has a teardrop shape. Enclosed in the exemplary abrasive tip 615 the two ends of the distal twisted wire are acutely separated to give an abrasive tip a larger diameter.

In some embodiments, out of the array 600 of tips, an exemplary abrasive tip 620 may, for example, be used to clean a large surface. The exemplary abrasive tip 620 has a brush shape. Enclosed in the exemplary abrasive tip 620 the two ends of the distal twisted wire are obtusely separated to give an abrasive tip a larger diameter. Some embodiments may be advantageously configured for large applications. Some embodiments may, for example, be configured for large (e.g., >3 inch) pipe fitting cleaning. In some embodiments, a tip may be configured for engine bore and/or head cleaning

In some embodiments, out of the array 600 of tips, an exemplary abrasive tip 625 may, for example, be used for the larger object. The exemplary abrasive tip 625 has a brush shape. Enclosed in the exemplary abrasive tip 615, the bent proximal end of the twisted wire may be coiled to give an abrasive tip a roller functionality. The roller functionality may allow for faster cleaning. Further, the roller may be spring-like, allowing the tip to twist and bend, so the abrasive tip becomes flexible. The spring-like functionality may, for example, be beneficial to keep the abrasive tip securely coupled to the twisted wire.

FIG. 7A and FIG. 7B show exemplary embodiments of a double-sided FACC 700. In various embodiments, the double-sided FACC 700 may extend the durability of a single FACC. For example, a user may use one tip of the FACC 700 after another tip of the FACC 700 may be worn out.

In some implementations, as shown in FIG. 7B, each end of the FACC 700 may include some wool materials. In some implementations, different wool materials may be used at each end of the FACC 700. For example, one end of the FACC 700 may be fine wool, and another end of the FACC 700 may be coarse wool.

In some embodiments, a double-sided FACC 700 may, for example, be configured with different size ends. For example, a small size may be used for small crevices, and a larger size may be used for larger surfaces. For example, the double-sided FACC 700 may be configured in some embodiments with different shapes. For example, one end may have a teardrop shape, and another may have a more pointed shape.

Accordingly, a user may use one double-sided FACC 700 to access various cavities and/or clean different deposits.

For example, the magnetic FACC 800 may capture steel wool filament that may fall off during use. FIG. 8 shows an exemplary magnetic FACC 800. The magnetic FACC 800 includes magnetic tips 805 a and 805 b, and a shaft 810.

As shown in FIG. 8 , the magnetic tip 805 a may include holes 815. In some implementations, the holes 815 may allow metallic particles to pass through toward a magnet 820 in the middle of the shaft 810 of the magnetic FACC 800. In some implementations, the magnetic tip 805 a and the magnetic tip 805 b may include metallic fibrillous abrasive material. For example, the metallic fibrillous abrasive material may be steel wool. In some examples, the magnetic tip 805 a and the magnetic tip 805 b may remove steel wool particles created during a cleaning process. Such embodiments may, for example, advantageously ‘self-clean’ debris from the FACC 800 during cleaning. For example, such embodiments may advantageously prevent metallic particles from contaminating a mechanism (e.g., clogging a carburetor jet or scoring an engine cylinder).

FIG. 9 shows an exemplary double-sided FACC 900 with a flex shaft 905. In some implementations, the flex shaft 905 may include one or more flexible joints such that the flex shaft 705 may be bendable to be used in various crevices and cavities.

FIG. 10 shows an exemplary injectable FACC 1000. In this example, the injectable FACC 1000 includes a cavity 1005 to store injected liquid 1005 a. In some implementations, the injected liquid may be penetrating oil for facilitating deposit removal from the cavity 105. For example, the injected liquid may be a lubricant (e.g., WD-40).

In the depicted example, the liquid is injected into cavity 1005. The liquid is injected into the cavity through a screw cap 1006. In some implementations, the handle 130 (e.g., stem) and the fibrillous abrasive tip 125 are squeezed against the cavity 1005, as shown by an arrow 1010 and an arrow 1015. In some examples, the liquid is dispensed towards the fibrillous abrasive tip 1020 via a dispensing hole 1020.

FIG. 11 shows an exemplary length adjustable FACC 1100. For example, the length adjustable FACC 1100 may selectively be extended and retracted in length along a vertical axis 1105. Along the top of the vertical axis 1105, a distal end 1105 a of the arrow is shown. Along the bottom of the vertical axis 1105, a proximal end 1105 b of the arrow is shown. In this example, a top portion 1110 of the length adjustable FACC 1100 may be selectively extended along the vertical axis 1105 as shown by an arrow 1115. The length-adjustable FACC 1100 includes, in this example, a middle portion 1120 that may be selectively extended along the vertical axis 1105 as shown by an arrow 1125. Accordingly, the length-adjustable FACC 1100 may be used to reach cavity surfaces at various distances from a proximal end of the length-adjustable FACC 1100.

In some implementations, some extendable portions may be included in a length-adjustable FACC. For example, a length-adjustable FACC may include only the selectively extendable top portion 1110 without the middle portion 1120. In some examples, a third selectively extendable portion may be included. In various embodiments, a length-adjustable FACC with more selectively extendable portions (e.g., telescoping) may increase the flexibility of the length of the FACC.

FIG. 12 shows an exemplary FACC 1200. The exemplary FACC 1200 includes a stem 1205. The exemplary FACC 1200 includes a fibrillous abrasive tip 1210. The fibrillous abrasive tip 1210 includes an insertion mechanism 1210 a. The stem 1205 and includes a receiving module 1205 a, containing a ball retainer. The stem 1205 includes a cavity 1205 b. Liquid may, for example, be stored in the cavity. The FACC 1200 includes a ball retainer 1215 in this example. The FACC 1200 includes a one-way valve in this example. The FACC 1200 may be made by inserting the fibrillous abrasive tip 1210 into the stem 1205 through the ball retainer and the one-way valve.

Although various embodiments have been described regarding the figures, other embodiments are possible. In some implementations, a FACC may include a fibrillous abrasive tip at one end and a jet reamer at the other. For example, a user may use the FACC to clean carburetor jets and bowls.

Although an exemplary system has been described regarding FIGS. 1-12 other implementations may be deployed in other industrial, scientific, medical, commercial, and/or residential applications.

Some implementations have been described. Nevertheless, it will be understood that various modifications may be made. For example, advantageous results may be achieved if the steps of the disclosed techniques were performed in a different sequence, if components of the disclosed systems were combined differently, or if the components were supplemented with other components.
